Geology 101 exam 1 WWU question with correct answers graded A+ 2023What is the lithosphere? - correct answer crust and upper mantle What is the asthenosphere? - correct answer the upper layer of the earth's mantle, below the lithosphere deformable--like playdough Continental lithosphere - correct answer -thick -old(4byo) -not dense -many types of rocks oceanic lithosphere - correct answer lithosphere that is mainly comprised of basalt; it is more dense that is why it sits lower in the asthenosphere. -thin -young(200 myo) 3 types of plate boundaries - correct answer 1. Divergent 2. Convergent 3. Transform Where is new ocean lithosphere created? - correct answer mid-ocean ridges (divergent plates) What is a hydrothermal vent? - correct answer an opening in the sea floor out of which heated mineral-rich water flows. Where do most earthquakes in the ocean occur? - correct answer mid-ocean ridges What is a divergent boundary? - correct answer the place where two plates move apart, or diverge; mostly occur along mid-ocean ridges and land magma fills space between plates What is a convergent boundary? - correct answer When two plates collide and one plate subducts What is a transform boundary? - correct answer a place where two plates slip past each other, moving in opposite directions What is an ocean-continent convergent boundary? - correct answer Ocean plate subducts under continental plate Creates a trench and volcanoes on continental plate What is continental rifting? - correct answer When a divergent boundary forms within a continent What is an example of continental rifting? - correct answer Great Rift Valley in East Africa What is Ocean-Ocean Convergent Boundary? - correct answer The denser oceanic plate subducts under the lighter one Creates a trench and volcanoes(islands) What type of boundary creates volcanoes? - correct answer Ocean-Ocean Convergent Boundary
